Abstract
A light-diverting catheter tip is provided according to embodiments disclosed herein. The light-diverting catheter tip may be coupled with the distal tip of a laser catheter and divert at least a portion of the light exiting the distal tip of the laser catheter such that the spot size of the laser beam on an object after exiting the catheter tip is larger than the spot size of the light entering the catheter without the catheter tip. The catheter tip may be removably coupled with the catheter or constructed as part of the catheter. In other embodiments, the catheter tip may conduct fluid and/or divert fluid at the tip of the laser catheter.
